DEVELOPMENT OF YAM MINISETT PROCESSING MACHINEPages 69-78
Abstract:
This study involves development and performance analysis of a yam minisett processing machine for effective yam production. The minisett cutting technology was developed to advance projectile cutting profile motion required for yam minisett processing as obtained in the native technique. The machine comprising the frame, speed reducer, pulley, belt, crank mechanism, connecting rod, hopper, seed yam carrier, cutting blades, and discharge chute, average length and breadth of the seed yams used for designing the minisett processing machine was also determined as 247.80mm and 66.75mm respectively. All materials used in the fabrication of this machine were sourced locally, and the estimated cost for producing one unit of the machine is Two hundred and eighteen thousand, five hundred naira only (N218, 500.00). Performance analysis results show that the crank shaft speed, connecting rod length and the number of blades were used as functional operational parameters while the machine capacity and efficiency are the functional performance indicators of this Yam minisett processing machine. The results show that the machine operates at an optimal efficiency and capacity of 96.24% and 28,888minsett/hr respectively, obtained at a crank shaft speed of 10-80rpm, connecting rod length of 470-540mm and cutting blade number settings of 13.
